Part 2, Chapter 2 Into Level 3 Summary

Dan Dalgard decides to call USAMRIID and sends samples of blood and spleen to a civilian virologist named Peter Jahrling. Jahrling dresses in surgical scrubs and takes the monkey meat into a Level 3 laboratory for tests. Somewhere along the line he jokes, "Good think this ain't Marburg."

While he and his assistants are growing the virus in test tubes full of monkey cells, Dan Dalgard learns that the animals in Reston seem to be doing better. His relief is short lived, as that night eight more monkeys die. Half the monkeys in room F are now dead. A few days later monkeys begin to die in other rooms, as well. Believing the animals have simian hemorrhagic fever, which is fatal to monkeys and harmless to humans, Dalgard euthanizes the remaining monkeys in Room F.
